1、隔音性能据资料表明，塑钢门窗的隔音性能大大优于铝合金门窗。比方说：

1, noise performance <br>Statistics show that noise performance is much better than steel doors and windows aluminum doors and windows. For example: to achieve the same noise requirements of the building, construction and transport corridors from the installation of aluminum windows and doors to be 50 meters away, if the steel doors and windows can be reduced to less than 16 meters. <br><br>2, thermal insulation properties <br>mentioned insulation performance, we need to compare the basic technical parameters of the material, for example PVC thermal conductivity material is 0.14, and the aluminum was 175. In other words, under the same conditions, in terms of material thermal conductivity, aluminum is 1250 times the PVC material. Of course, if the doors and windows made of PVC, conducted comparing the energy consumption, it is difficult to generalize. Because the indoor heat loss, usually associated with roof, floors, walls, and doors and windows. However, research data show that as an ordinary house, the same open air, installed steel doors and windows of the room than the room installed energy-saving aluminum doors and windows every day to more than 5 degrees. <br><br>3, the corrosion resistance of <br>steel doors to acid, alkali and other corrosive chemicals, it is not afraid of erosion urban pollution, acid rain and the like, and hydrochloric acid. The aluminum is not, after the case of easily lead to surface oxidation corrosion and shorten life. <br><br>4, the installation performance and service life of the windows <br>steel doors is much lower than the weight of aluminum windows and doors, but because it is integrally formed, quickly installed, so that the overall efficiency is greatly improved. Aspects of life, steel doors and windows of the normal service life of 30-50 years, lower than the aluminum doors and windows. <br><br>5, process performance and product design <br>steel doors and windows and aluminum doors and windows can be designed according to the requirements of the designer made into flat open, sliding, and the curved windows hung, Fang Xinying large attractive appearance. Steel doors and windows can be colored surface, coating, coextrusion multicolor; aluminum doors and surface coating, electrophoresis, color can be achieved also diversified.

1, soundproofing performance<br>According to the data, the soundproofing performance of plastic steel doors and windows is much better than that of aluminum alloy doors and windows. For example, buildings that meet the same noise requirements, the distance between buildings with aluminum alloy doors and windows and traffic trunks should be 50 meters away, and if plastic steel doors and windows can be shortened to less than 16 meters.<br><br>2, thermal insulation performance<br>When it comes to insulation, we need to compare the basic technical parameters of the material, e.g. the thermal conductivity of PVC materials is 0.14, while the aluminum alloy is 175. In other words, under the same conditions, aluminum is 1250 times the pvc material in terms of material thermal conductivity. Of course, it is difficult to generalize if PVC is made into doors and windows for energy consumption comparison. Because of the heat loss in the interior, it is usually associated with roofs, floors, walls, and doors and windows. However, scientific research data show that, as an ordinary residential, the same open air conditioning, plastic steel doors and windows of the room than the room installed aluminum alloy doors and windows to save electricity more than 5 degrees per day.<br><br>3, corrosion resistance<br>Plastic steel doors and windows can withstand acid and alkali and other chemicals corrosion, so not afraid of urban environmental pollution, hydrochloric acid and acid rain erosion. Aluminum alloy is not the case, in the face of corrosion easily lead to surface oxidation, shorten the service life.<br><br>4, door and window installation performance and service life<br>Plastic steel doors and windows weight is much lower than aluminum alloy doors and windows, but also because of the overall molding, installation speed is very fast, so that the overall efficiency greatly improved. In terms of service life, the normal service life of plastic steel doors and windows is 30 to 50 years, lower than aluminum alloy doors and windows.<br><br>5, product style and process performance<br>Plastic steel doors and windows and aluminum alloy doors and windows can be made according to the design requirements of designers into a flat open, push and pull, hanging and curved windows, beautiful and elegant novel. Plastic steel doors and windows surface can be coloring, coating, multi-color co-crowding;

1. Sound insulation performance<br>According to the data, the sound insulation performance of plastic steel doors and windows is much better than that of aluminum alloy doors and windows. For example: for buildings that meet the same noise requirements, the distance between the buildings with aluminum alloy doors and windows and the main traffic road should be more than 50 meters, and if plastic steel doors and windows are used, it can be shortened to less than 16 meters.<br>2. Thermal insulation performance<br>When it comes to thermal insulation, we need to compare the basic technical parameters of materials. For example, the thermal conductivity of PVC material is 0.14, while that of aluminum alloy is 175. That is to say, under the same conditions, aluminum is 1250 times more than PVC in terms of thermal conductivity. Of course, if PVC is made into doors and windows to compare energy consumption, it is difficult to generalize. Because the indoor heat loss, usually with the roof, floor, walls and doors and windows. However, according to scientific research data, as an ordinary house, the room with plastic steel doors and windows can save more than 5 degrees of electricity per day than that with aluminum alloy doors and windows.<br>3. Corrosion resistance<br>Plastic steel doors and windows can resist the corrosion of acid and alkali and other chemicals, so they are not afraid of the corrosion of urban environmental pollution, hydrochloric acid and acid rain. However, aluminum alloy is not so easy to cause surface oxidation and shorten service life in case of corrosion.<br>4. Installation performance and service life of doors and windows<br>The self weight of plastic steel doors and windows is much lower than that of aluminum alloy doors and windows. Moreover, due to the overall forming, the installation speed is very fast, which greatly improves the overall work efficiency. In terms of service life, the normal service life of plastic steel doors and windows is 30-50 years, lower than that of aluminum alloy doors and windows.<br>5. Product style and process performance<br>Plastic steel doors and windows and aluminum alloy doors and windows can be made into flat open, push-pull, hanging and arc windows according to the design requirements of the designer, with beautiful and novel shapes. The surface of plastic steel doors and windows can be colored, coated and multi-color coextrusion; the surface of aluminum alloy doors and windows can be sprayed, electrophoretic and diversified in color.
